DYEING-MACHINE.

I Specification of Letters Patent.

" Patented Oct. 13,1914.

Application filed October 16, 1911. Serial No. 654,922 g i To all whom it may concern: I

Be it known that I, ROBERT D. BOOTH, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements n Dyeing-Machines, of which the following is a specification.

In dyeing permeable materials varlous types of machines have been used and among these is the machine set forth in'the patent to John T. Psarski No. 955,993 granted April 26, 1910, and in many of these machines, the paths of travel of the dye liquor established by the inlet and thedischarge are of uneven lengths. This is true of the paths of travel set up in the Psarski patent by the openings in t e false bottom, and in the dome adjacent to the base of the dome as the distance from this point to the discharge is much greater than it is from the other liquor supply openings in the dome and in the fase bottom to the discharge, and this unequal length in the paths of travel of the liquor requires that the machine shall be operated in an extremely careful manner to avoid the splitting of the batch when the liquor flows more readily through one portion than through another. 1 lhe object of the present invention, therefore, is to provide a construction of dyeing machine wherein the paths of travel of the dye liquor shall converge from the inlet toward substantially the center of the discharge, and whereby they shall be substantially equal whereby a substantially uniform resistance is set up to the dye liquor throughout the entire tank, with the result that an even dyeing of the mass results and the splittingof the batch is avoided. v

'More specifically the invention relates to l a tank or kettle provided with a cover having an annularly disposed group of rows of perforations, and a distributing member within the tank and having a foraminous discharge portion'conforming to an are described about substantially the center of the discharge.

' l I Theinvention may be still further briefly summarized as consisting in theconstruction and comblnations of parts heremafter set forth in the following description, drawings and claims.

' Referring to the drawings, Figure 1 illustrates one form of my invention partly in section; Fig. 2 is a to planview of a portion of the cover; an Fig. 3 is a top plan giew of a portion of the distributing memp In carrying out the invention any preferred form and construction of parts may be employed so long as they possess the'necpipe 4 leading to the outlet of a centrifugal pump 5. This pump is connected at its in-. let, by means of a pipe 6, with a three-way valve 7 arranged between a pipe 8 leading to an opening 9 in the bottom of the tank, and

a pipe 10 leading to an opening 11 in the side of the tank near the top. This piping and pump are for thepurpose of establishing a circulation in any direction butduring the dyeing operation it is preferable to cstablish a circulation up through the pipe 1 into the center of thejtank. A suitable steam pipe connection 12 may be placed above the bottom of the tank for the purpose of heating the liquor. The inner 'wall of the tank may be provided with openings 13 for receiving clips 14 for a purpose to be described. The tan'k'is further provided with a shoulder 15 at its bottom. Resting upon the shoulder 15 isa distributing member comprising a central portion 16 having an openinn for receiving the shank 17 of aflbolt 18 whlch passes up above the top/of the machine. This boltis held in pla'ce by. a nut 19. This central portion 16 is provided witha downwardly and outwardly extending flange-20 Which .is curved inward on the downwardslope in an are described about the center of the discharge to be described.

This portion 20 restsupon the shoulder 15.

Resting upon a gasket 21 on top of the cen tral portion 16 -is a cover 22 having an openmg 23 at the center for thepassage of the bolt 18 and provided nearits periphery/with rows of openings 24- which form the dis charge, and it is the main point between the circle passing through the centers of the inher row of holes and the circle passing throughthe centers of the outer row of holes which forms the center. of the are described by the forarninous portion20 ofthe distributing member. This cover is engaged by the clips 14 which hold it in place. A suitable nut 25 upon the bolt 18 serves to hold this cover tightly down upon the central portion of the distributing member.

In operation, the material is packed in the annular chamber formed between the distributing member and the side of the tank, the cover is then placed in the machine and secured, and the pump is started with the result that the dye liquor is forced up into the chamber formed within the distributing member, from whence the liquor is directed outwardly from the center and upwardly from the bottom to the discharge, the supply openings in the distributing member being all substantially equidistant from the central point of the discharge. In this Way all of the material is evenly dyed by reason of the even length of travel of the liquids in the directions in which it must pass.

Very important features among these produced by the foregoing construction are, first, the fact that the liquor is caused to pass through the entire mass uniformly, and second, in starting the material in all parts of the machine is under substantially the same influence of the dye liquor, that is, a circulation is set up in starting which tends to crowd all portions of the material toward the imperforate areas on either side of the discharge and toward the discharge, thereby doing away with the splitting of the batch, or in other words, preventingthe floating of portions of the material on the face thereof adjacent the inlet. Having described my invention,I claim :-1

1. In apparatus for dyeing permeable material by forcing dye carrying liquor through the same, a receptacle forming a chamber for receiving the material to be dyed and having a discharge with an imperforate area on each side thereof, and mass forming and liquor supplying means having liquor distributing; openings opposed to the discharge and the imperforate areas, said mass form ing and liquor supplying means,'said dis charge, and said imperforate areas being relatively located to establish substantially ,equal paths of travel for the dye liquor and to produce a resultant circulation for forcing the material against the imperforate areas and toward the discharge, and means for circulating the dye liquor.

2. In apparatus for dyeing permeable material by forcing dye vcarrying liquor through. the same, a receptacle forming a chamber, for receiving the material to be dyed and having a foraminous discharge portion bounded by a non-foraminous portion, and liquor supplying means, each point of liquor inlet thereof being substantially equidistant from its opposed point of dis- ,charge and all of said liquor inlets being substantially in opposition to a non-foraminous portion, and means for circulating the dye liquor.

3.
